Hi, is there any specific rules of thumb re the lower edge of the rear landslide relative to the lower edge of the moldboard? Only I am doing away with a rolling landslide and have a much longer one to take it's place however it is meant for another style of plough of the same make. I cannot get (as far as I am aware) a long landslide for the plough I am making up ( A fergie Lea plough) I had hoped the DB long landslide may have fitted but Westlakes say no. However I have a nice landslide to bolt on but to me it seems to protrude a fair way below the lowest part of the moldboard, so I will either weld up and re-drill the frog or just plasma a strip off the bottom edge. I would have thought it should be ever so slightly lower than the lowest part of the moldboard but am not 100% certain, hence the question here, anyone have any pointers?
